The builds 157-159

16.0.159 (8/24/2011)

1. Fixed: Empty numeric searches were not working (only applies to 158).
2. Fixed: Regular expressions were not working (only applies to 158).
3. Fixed: Some math functions would not work properly in expressions (only applies to 158).
4. Changed: The mute state of a zone will not be cleared on startup if "Options > Startup > Optimize volume for best sound quality" is not checked.
5. Fixed: Naming two Theater View library items the same could cause problems.

16.0.158 (8/23/2011)

1. Fixed: The expression language could fail to parse some expressions properly due to changes in 16.0.157.
2. NEW: Added an optional flags parameter to the Regex(...) expression function. Use the flag "1" to perform case sensitive matching.
3. Changed: Czech language translation updated (thanks to Johnny B).
4. Faster: Optimizations to core database search engine. Long searches can be 10 or more times faster to execute.
5. Fixed: Panes weren't working properly with dates before 1900.
6. Changed: Audio stream selection for videos will preserve the default selection made by a splitter if the language of the selection matches the user's language selection in Media Center's options.
7. Changed: Minor tweak to how playback checks for file system permissions and ownership when starting playback.
8. NEW: DSP Studio > Parametric Equalizer has two user channels that can be used to hold temporary data. For example, you could combine Left and Right into User 1, equalize User 1, and then add the result to the Subwoofer.
9. NEW: Subtitles are fully supported when converting for Gizmo (sizing, position, and subtitle selection honor playback settings).

1. Fixed: DVD playback could start with a black screen.
2. Fixed: Expressions using /# #/ to mark unescaped text could still have certain characters get escaped.

4. Changed: Regex(...) captures for the last run Regex(...) are accessible with variables [R1], [R2], up to [R9].
5. Changed: Regex(...) can be used to perform a test by setting the last parameter to 0 (the default) and it will return 0 or 1.
6. Changed: Regex(...) uses case insensitive regular expression matching.
7. Changed: Updated the French language translation (thanks to Dominique COMET).
8. Changed: Reduced how likely Play Doctor is to use the same file again when it's been used recently.
9. Fixed: The space bar and backspace key are routed to the search when using the search in Netflix, YouTube, or Hulu in Theater View.
10. Fixed: Pressing the space bar could cause two spaces to be output in Theater View > Gadgets > Search.
11. Fixed: Returning from Playing Now to a zoomed in file info panel in Theater View could show a remnant of a list.
12. Changed: Updated to LAV 0.33 filters with Red October (fixes a possible crash with PCM audio).
13. Changed: When pausing or unpausing playback, the system sleep and display timers are reset.
14. Changed: The screensaver is allowed while fullscreen playback is paused.
